High on the Qinghai-Xizang Plateau, often called the “Roof of the World,” a new species of snake waits beneath the stones…
Scientists from Yibin University and collaborating institutions have formally described Indotyphlops gyirongensis, the Gyirong blind snake, a discovery that adds a new member to one of the least understood branches of the snake family tree.
Blind snakes are small, burrowing reptiles that spend nearly their entire lives underground. Their secretive habits and similar appearances make them notoriously difficult to study.
The family Typhlopidae contains roughly 280 species, yet its relationships remain poorly resolved, and new species continue to surface wherever researchers look carefully. Until now, no blind snake had ever been recorded in the Xizang Autonomous Region, which makes this find a first for the area.
The single specimen, an adult female, was collected in August 2025 at an elevation of 2,262 metres, close to the border between China and Nepal. She was resting beneath a stone at the edge of an evergreen broad-leaved forest, where deep humus and a thick layer of fallen leaves create ideal conditions for a creature that lives by burrowing. Among her neighbours were a Himalayan pit viper and a Himalayan toad!
The snake itself is slender and elegant. At 265 millimetres, it is large by the standards of its genus, yet it measures just 3.5 millimetres across at midbody. Its glossy scales are light brown, each one darker on its rear half, which gives the body a delicate and finely patterned sheen. The underside is cream and so thin-skinned that it is partly transparent to the internal organs.
Most distinctive is its pale cream head cap, which lacks pigment as far back as the eye. The eye itself is only a dark spot, with no visible pupil or iris, fitting for an animal that navigates by touch and chemical cues rather than sight. Its tail ends in a small nubbin rather than a sharp spine.
Some of the most telling differences are hidden in the arrangement of the scales along the lip. Blind snakes are classified partly by how their upper lip scales overlap the shields above them. In nearly all of the snake’s relatives, the third scale overlaps the one beside the eye, a pattern known as T-III.
The Gyirong blind snake shows a rarer arrangement, called T-V, in which both the second and third lip scales overlap the shields above. Few documented members of its genus share this feature, which provides a clean and reliable way to separate it from most of its kin.
Anatomy alone did not settle the matter. The team sequenced two mitochondrial genes and placed the snake within a broad evolutionary tree. It nested firmly within Indotyphlops, as the sister lineage to I. albiceps, but its genetic divergence was substantial. For one gene, it differed from its closest relatives with available data by more than 24 per cent, and for another by more than 18 per cent, margins far beyond what is typically seen within a single species.
The name honours the place of discovery. Gyirongensis refers to Gyirong Town in Gyirong County, where the holotype was found, and it is formed as a noun in apposition. The authors propose the English common name “Gyirong blind snake” and the Chinese name 吉隆盲蛇 (Jílóng Mángshé).
Because the type locality sits so close to the Nepalese border, the researchers consider it highly likely that the species also lives on the other side, thus pending further fieldwork.
